6 Motion/Forces

when an object speeds up, slows down, OR changes direction

• velocity

• position

• force

• acceleration

the change of position and direction from the starting point

• acceleration

• potential energy

• frame of reference

• displacement

the amount of change in a position

• displacement

• speed

• friction

• distance

push or pull acting on an object

• distance

• vector

• inertia

• force

where an object is relative to something else

• force

• velocity

• kinetic energy

• frame of reference

a force that opposes motion between any surfaces that are touching

• frame of reference

• acceleration

• mass

• friction

the tendency of an object to resist a change in its motion

• friction

• displacement

• Newton (N)

• inertia

the energy of moving matter

• inertia

• distance

• position

• kinetic energy

the amount of matter in an object

• kinetic energy

• force

• potential energy

• mass

The SI unit for force

• mass

• frame of reference

• speed

• Newton (N)
